Why am I not surprised that Brad avoided his responsibility to tell JJ about his parentage. No one's reactions are surprising, JJ finding out the people around him really did let him down is gonna strike out at all of them for not at least clueing him in even if they themselves didn't know the answers. And of course Will is hurt when he's been the best of all of them about being in JJ's corner, but he knows JJ's basket case mentality and will soon realize JJ is just wrapped up in the moment, JJ predictably being JJ. Except it shows that JJ is starting to grapple with what deep down he must have long wondered, even if unwilling to actually think it.
